Patented June 9 193i UNITED STATES OTTO KUBATZKY, OF TULSA, OKLAHOMA WINDOW VENTILATOR Application filed January 6, 1930. Serial Ito. 418,869.

This invention relates to improvements in window ventilators.

The primary object of this invention is the provision of an improved type of window ventilator, possessing some of the general characteristics of the ventilator of my application, Serial No. 338,555, filed February 8, 1929, but differing thereover in the relation in which the improved ventilator is mounted within a lower portion of a window sash; embodying improved means to adjustably retain the ventilator in a desired ventilating adjustment; embodying improved screening means to permit of ventilating a room without the admission of flies and foreign materials into the room; embodying an improved weather stripping arrangement; and including improved lock means.

Other objects andadvantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a front elevation of the improved ventilator, showing its location with respect to a sash.

Figures 2 and 3 are cross sectional views taken substantially on their respective lines in Figure 1 of the drawings.

Figure 4 is a sectional view similar toFigure 3, with the ventilator in open adjusted relation in the sash.

Fgure 5 is a fragmentary perspective view of a portion of the improved ventilator.

Figure 6 is a sectional view taken substantially on the line 6-6 of Figure 3.

Figure 7 is a sectional view taken through the lower portion of a sash in which the ventilator is positioned, showing the ventilator removed and more particularly illustrating the retaining trough and Weatherstripping arrangement of the sash.

Figure 8 is a fragmentary perspective view of an end portion of the trough or base of the ventilator.

In the drawings, wherein for the purpose of illustration is shown only a preferred embodiment of the invention, the letter A may generally designate the improved ventilator, which is used uponv a frame B. In the present instance the frame B is a window sash, but may be any other frame through which ventilation is to be passed, such as a door frame or the like.

The sash B includes a lower rail or stile 10, and side stiles or frames 11. The window pane 12 is secured against the beads 13 of the side rails ofthe window sash in conventional relation, except that at its lower edge it terminatesv short of the lower rail or stile 10, at any approved distance, to define an opening 15 through which a ventilating draft passes, as permitted by the ventilator A.

The improved ventilator A preferably comprises a supporting base 16, preferably of sheet metal, which is of trough-like formation, and which. movably supports the main draft deflecting shield 17. End shields 18 7 are connected to the main draft deflecting shield 17 in a' relation which will permit the oscillatory movement of the shield structure upon the base 16; the end shields 18 constituting the frame of the windshield apparatus 7 5 also detachably receiving a perforated screen structure 19 adapted for a novel cooperation association with the pane 12 as protective means during the ventilating inclination of the shield 17.

The base piece 16 is preferably of sheet metal, stamped or other-wise bent to form, and it includes a trough consisting of a bottom wall 20. The bottom wall 20 is normally horizontally positioned, and it has an upstanding wall 21 normal thereto, along one longitudinal edge and along the opposite longitudinal edge is provided with a deflecting wall 22 divergent with respect to the wall 21. The walls 21 and 22 provides a trough- 90 way longitudinally upon the top edge of the bottom rail 10 of the window sash, within which the lower edge of the ventilator shield 17 rests,and wherein water is received to prevent the admission thereof to the room. The wall 21 is of material doubled upon itself, and the outer layer of material is extended be low the plane of the base 20, as shown at 23 in Figure 8 of the drawings, and along its lower edge it is provided with a right angled attach- 100 ing flange 24 adapted to lie within the normal groove of the rail 10, as shown in the drawings; the same having openings 25 therethrough to receive attaching elements 30 The wall 21 adjacent the ends of the trough is removed, above the bottom 20, to provide Ways 27, shown in Figure 8, through which water may flow outwardly, that is, to the outer side of the room, so that water will not overflow the tops of the trough walls. The trough 16 at the ends thereof is provided with retaining walls 28, similar to that shown in Figure 8. As is well understood from the drawings the attaching flange 24 is secured by nails, shown in Figure 6 at 30, upon the rail 10, to position the trough with an upwardly facing groove wherein the lower marginal portion of the movable ventilator A is received in the relation which is perfectly apparent from the foregoing.

The end shields 18 are preferably struck from sheet metal, each consisting of a segmental body portion 30 which is convexly arcuated at the upper edge thereof, for detachably receiving thereon the screen structure 19 in a well supported relation. On the outer longitudinal edge of each end shield 18 there is provided a flange 33, normal to the plane of the body 30, extending in'the direction of the side stile of the window frame C wherein the sash is mounted; this flange 33 extending from adjacent the lower narrow end of the body 30 to the upper margin thereof whereon the screen 19 is clamped, as shown in Figure 5. Along the opposite longitudinal edge, the body 30 has integrally or otherwise connected therewith a substantially channeL shaped socket 36, projecting from the inner side of the plane of the body 30, normal thereto, and of course at the opposite side from that side to which the flange 33 projects. It defines a socket opening 37 adapted to receive a side margin of the deflecting shield 17 as shown in Figure 2 of the drawings. The channel 36 at the outer side of the respective end shield 18 upon which formed is transversely conv-exed, bulging longitudinally beyond the plane of the outer surface of the body 30, upon which positioned, for releasable snap action with a suitable socketprovided in the weather stripping 40 provided on the faces of the side frame rails or stiles of the sash B, for the purpose of holding the ventilator in an inoperative relation and sealing the ends of the same with the sides of the window sash to prevent entrance of water and draft through the room.

The imperforate shield 17 is preferably of glass, although it may be of any approved material, even sheet metal. It may preferably be of plate glass, and along the margins thereof it is detachably secured in the channel groove 37 of the channels 36 of the end shields 18. The main shield 17 along the upper marginal portion thereof. projects upwardly above the top of the end shields 18, and above the screen structure 19, in a relation which permits of the same overlapping with the lower marginal portion of the main body 12 of the window sash pane, as is shown in Figure 3 of the drawings.

The weather strips 38 are of the channelshaped construction, and attached to the inner faces of the window wash rails 11 at the portions which confront the opening 15 within which the'ventilator operates. These channel-shaped weather strip pieces 38 are preferably of metal, and include the attaching flanges 40 and 41 adapted for respective placement at the outer and inner sides of the rail 11 of the sash, with the body &2 extending across the inside face of the sash and there providing offsets which may conform to the beading on the sash, and including a longitudinal depression or groove 44L wherein the convex part of the socket of the end shields 18 may snap to provide a leak-proof connection between the weather strip 38 and the end shield, as is shown in Figure 2 of the drawings. This portion 42 has a right angled offset 15 facing the outer side of the window sash, against which the retaining flanges 33 of the end shields 18 contact to limit the open movement of the ventilator, as shown in Figure 1.

The main shield 17 is provided with a retaining latch 50, comprising a shaft 51 hearing in a suitable bushing 52 supported in the shield 17 at a location just below the lower edge of the pane 12 of the sash. The bushing 52 is enlarged at the inner side of the shield 17 and receives a spring 54 therein. The shaft 51 at the inner side of the shield 17 has a knob or handle 55 bearing against the spring 54 in the socket of the bushing 52. The shaft 51 extends to the outer side of the shield 17 and there is suitably provided with a transversely extending bolt 55 which upon turning the shaft 51 may move into or out of shield retaining relation with the rear side of the lower margin of the pane 12 of the sash, as shown in Figure 3 of the drawings. The spring 54 normally urges the padded side 56 of the bolt 55" into a frictional position against the pane 12 for the purpose of holding the lower edge of the pane 12 in close abutment, as shown in Figure 3, during a closed position of the ventilator.

Referring to the screen structure 19, the same is of quite different arrangement than that of the screen structure of the application above identified. It is placed on top of the ventilator, rather than to the outer side thereof. The screen structure 19 preferably includes a metal supporting frame 60, including the outer and inner parallel rail portions 61 and 62, and the end portions 63; the latter of which are secured to the end shields 18. Between the portions 61, 62 and 63 the frame defines an opening wherein perforate screening 64, of fine mesh material, is disposed. In general cross section the screen 19, transverse to the plane of the window sash, is concavo-convex and adapted to snugly fit against the lower edge of the pane 12 during movement to opened, closed, or adjusted ventilated position, as shown in Figures 3 and 4 of the drawings. The end portions 63 of the screen frame 60 are of metal, and are provided with depending flanges at the ends thereof, generally designated at 67 in Figure 6 of the drawings, having substantially an S-shaped cross section and defining upwardly opening guide grooves 68 and a downwardly facing socket groove 69; the latter of which receive the upper portions of the body 30 of the end shields 18 therein, in a snug and tight-fitting, yet preferably detachable relation, as shown in Figure 6. The grooves 68 are relatively wide. Along the upper edges thereof, the flange structure 67 above the socket 69 is transversely notched at a plurality of places, as designated at 7 O in Figure 5 of the drawings. These notches 70 are adapted to receive a portion of a detent lever 7 2, shown in Figure 1, pivoted at 73 upon the inner side of a rail 11 of the sash, and having a handle 7 4; for convenient manipulation.

Each of the side rails or stiles 11 on the window sashes are provided with retaining members 80, secured as shown in Figure'6, at 81, to the sash opening facing sides of the stiles 11, including portions extending transverse thereto, and having depending retaining ends 81 operating in the slots or grooves 68 of the ends of the screen 19, to provide a tie-in which will guide the efficient action of the ventilator during movement, as can be seen from Figure 6 of the drawings, and elsewhere; To prevent outward displacement of the screens 19, from the end shields 18, the latter are provided with retaining lugs 85,shown in Figure 5, adapted to engage the rear or outer edges of the flange portions 67 of the ends of the screen flange 50. Of course, the flanges 36 prevent opposite movement of the screens 19 from the end shields 18.

It will be noted from Figures 1, 3 and 4 of the drawings that the rail or beam portions 62 of the screen frame are oflset downwardly at 90, providing a depression wherein the bolt 55 of the latchmember 50 may operate, and so that there shall be no opening in the screen member 19, as would likely admit insects, foreign materials and the like during a ventilating or other position of the ventilator A.

Various changes in the shape, size, and arrangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the scope of the claims.

I claim:

1, In a ventilating structure of the class described the combination of a sash including a frame having a window pane therein spaced from a portion of the frame to pro- 1 vide an opening, a main shield, side shields at the ends of the main shield, means mounting the lower margin of the main shield and the side shields in a movable relation in the openings of said sash to shut off or permit passage of a draft through the opening of the sash, guide members carried by the frame at the upper portion of the opening, and means providing guide channels in the end shields wherein said members project for stabilizing the end shields and main shield in operating movement during ventilating adjustment thereof.
